We claim- 1. A meat-chopper comprising a frame having a receiving-hopper and a lateral outlet, a cutter-shaft journaled in said frame and located in said outlet, said shaft and outlet having cooperating cutting members, one end of the cutter-shaft projecting through a bearing formed at one end of the casing, a gear detachably secured to the projecting end of the cutter-shaft, the cutter-shaft being removable from said gear and through the bearing and outlet, a driving-shaft journaled in a bearing on the supporting-frame and provided with a gear, and an intermediate gear meshing with the gears on the driving and cutter shafts and located below the said detachable gear, whereby the intermediate gear is adapted to prevent downward displacement of the detachable gear when the cutter-shaft is removed therefrom, means being also provided for preventing lateral displacement of said gear after removal of the cutter-shaft.

2. A meat-chopper comprising a frame having a receiving-hopper and a lateral outlet, a cutter-shaft journaled in said frame and located in said outlet, said shaft and outlet the cutter-shaft,the cu tter-shaft being remov 4o able from said gear and through the bearing and outlet, a driving-shaft journaled in a bearing on the supporting-frame and provided with a gear, an intermediate gear meshing with the gears on the driving and cutter shafts and located below the said detachable gear, whereby the intermediate gear is adapted to prevent downward displacement of the detachable gear when the cutter-shaft is re moved therefrom, and a hood affixed toithe go supporting-frame and inclosing sa id gears, said hood cooperating with the int'tggi fiiediate gear in preventing lateral displacement of the detachable gear and having an opening which permits access to the device which secures the detachable gear to the cutter-shaft. In testimony whereof we have affixed our signatures in presence of two witnesses.
